DAVID GENESE, OF BALTIMORE, MARYLAND.

A.? FOR MILK BOTTLES.

Application fifled June 28, 1923.

To all whom it may concern:

Be it known that I, DAVID GnNnsn, a citizen of the United States, residing at Baltimore city, in the State of Maryland,have

invented new and useful Improvements in Caps for Milk Bottles, of which the following is a specification.

This invention relates to caps or stoppers for bottles, jars and the like and designed particularly for closing milk and cream bottles.

The primary object of the invention is to provide a cap or closure of pasteboard or cardboard ordinarily used for this purpose and having a disk contour with means of a positive character for applying and removing the cap or closure and centrally applied to the latter in such manner as to effectively close the aperture or slot through which the improved means partially extends, to thereby prevent ingress to the contents of the bottle or ar or deleterious germs or any matter that would in the least injure or contaminate the contents of the bottle or jar with 5' which the improved capor closure is used.

A further object of the invention is to provide means in connection with a pasteboard or cardboard cap or closure for a bottle or jar that may be readily secured to the cap or closure and having such positive fixed association with the latter as to permit repeated use of the cap or closure without liability of injury to the latter, and whereby the bottle or jar mouth or neck may be closed after use of a portion of the contents of the bottle or jar. A still further object of the invention is to economize and generally improve the manufacture of caps or closures for milk bottles, jars and the like by using a non-corrosive applying and removing means which is associated with the cap or closure and may be formed of metal, pasteboard, cardboard or other noncorrosive or neutral material with respect to H the contents of the bottle or jar and which also acts to reinforce the portion of the cap or closure to which it is applied.

With these and other objects and advan tages in view, the invention consists in the 90 construction and arrangement of the several Serial No. 648,374.

parts of the difi'erent forms of the improved device which will be more fully hereinafter described and claimed.

In the drawing:

Fig. 7 is an edge elevation of a cap or closure with the improved gripping means applied thereto and preferably formed of paste'board or cardboard; and

Fig. 8 is a transverse vertical section on the line 88, Fig. 7.

The numeral 5 in all of the forms of the improved gripping means as shown in the drawings designates the cap or closure, which is in the form of a disk of suitable dimensions that may be varied in accordance with the mouth of the bottle, jar or other device to which it is adapted to be removably applied. The cap or closure 5 will be manufactured as usual by suitable cutting dies, and while it is preferred to use pasteboard or cardboard in the manufacture of the disk, cap or closure 5, it will be understood that any other material adapted for this purpose may be used.

The invention particularly resides in a gripping device generally designated by the numeral 6 and may be formed of metal, pasteboard, cardboard or other material of a character that will not in the least contaminate or injure the contents of the bot tle or jar to which the cap or closure having the improved gripping means may be applied. For the purpose of illustration, let it be assumed that the improved gripping means as shown by Figs. 1 to 6, inclusive, is formed of metal, which is coated or tinned or may be made of sheet metal commercially known as tin and consisting of a base metal with a tin coating. Referring particularly to the form shown by Figs. 1 to 6, inclusive, the improved gripping means comprises a main body 7 of substantially rectangular form, as shown by Fig. 5, and having oppositely extending securing members 8 of less width than the body and formed with reduced or tapered extremities 9. The body is centrally bent or folded in a transverse direction, to provide side members 10 continuous with a top loop or roll bend 11, the members 8 depending from. the body members 10 an equal distance and normally in parallel relation. Owing to the material ditl'erence in width 01 the securin members 8 andthe body members '9, closing shoulders 12 are provided at each side of the securing members 8, and when the improved gripping means isshaped as shown by Fig. 4, these shoulders present a considerable hearing. or. covering projection at each side of the centrally located securing means or members. The roll or bend 11 at the top facilitates positive gripping of the improved device and also strengthens the general structure. In applying the improved grip ping means as shown by Figs. 1 to 5, ini-lusive, the reduced extremities 9 of the se rurin'g members 8 aretorced through a narrow slot or cut 13 formed in the center of the cape, and when the shoulders 12 are iorced downwardly and held in close contact with the upper surface of the cap adjacent to opposite extremities of the narrow slot or cut 13, the securing members 8 are spread and bent fiat in opposite directions ainst the underside of the cap, as shown liy Fig. 3. hen the gripping means is thus secured to the cap, the narrow slot, cut or puncture that may be formed by "forcing the securing members 8 with their reduced extremities 9 through the cap is fully closed and covered and also filled, so that there are no openings or crevices tliroughwhich deleterious germs or matter may enter the bottle or jar when the improved cap has been applied. "When the imrove'd gripping means has been applied and secured to the cap as just explained, there is ample projection thereof above the top or" the cap, to facilitate grasping the same and removing the cap and also for subsequently reapplying the cap. When the improved gripping means is formed 01": metal and the securing members 8 with their reduced extremities 9 are bent over against the underside of the cap as shown by Fig. 3, it will be unnecessary to use any additional securing medium to retain the improved gripping means in fixed relation to the cap or to prevent the same from working loose.

In Fig. 6 the improved gripping means will be essentially of the same structure as shown by Figs. 1 to 5, inclusive, With the exception that the upper bend or roll 11 is omitted and the body or the gripping means is formed of two thicknesses of metal, as at 1 1-, the blank used in producing the form of the improved gripping means as shown by Fig. 6 having the body thereof doubled in length with respect tothe body 7 as shown by Fig. 5. The object of this modification is to give a greater bearing extent of the improved gripping means in a transverse direction relatively to the top surface of thecap or closure 5.

in Fig. 7 the gripping means is of the same shape as shown by Fig. 5 without the bend or roll 11 at the top and is preferably formed 01 paper. The upwardly projecting portion of the gripping means in Figs. 7 and 8 has the two body members 15 drawn closely together in flat relation ,vvith the securing members 16 extending at right angles away therefrom and firmly fixed against the lower side of the cap or closure 5 by a suitable cementitious substance such as parafiin or a paste which will notin the least affect the contents of the bottle or jar to which the cap or closure may be applied. It is also proposed in fixing the securing members of the paper, pasteboard or cardboard form of the device as shown by Figs. and 8 to subject the same to heat pressure after the cementitious matter has been applied, or a suitable coating of combined protective and cementitious substance may be applied over the lower side of the cap after the securing members 16 have been bent outwardly in opposite directions, to. insure a positive retention of the paper, pasteboard or cardboard gripping means to the cap or closure. It will be understood that in applying this cementitious substance or whatever material that may be used and adapted for the purpose, the quantity thereof will be minimized and hardly perceptible when applied, and the mode of applying this cementitiou's material may be varied without in the least modify ing the features of the invention. The paper, pasteboard or cardboard form of the improved gripping means as shown by 7 and 8 will be effective and cheaper in its application than the metal form hereinbefore described, but obviously would not be as durable as the metal form. I

In all of the forms of the improved device one of the essential features of common construction therein is the shouldered bearing provision at opposite sides of the securing members to firmly engage the top of the cap or closure and prevent the improved gripping means from being forced through the cap or closure a greater distance than is desired, particularly when forcing the cap or closure 5 having the improved gripping means applied thereto into the neck or mouth of a bottle or jar. The shoulders projecting equally on opposite sides of the securing members give an equal bearing pressure on opposite sides of the center of the cap or closure beyond the terminals of the slot, cut or puncture through which the securing members are inserted, and when the securing members with their reduced penetrating extremities are inserted through the cap or closure and opened and bent flat in reverse directions against the underside of the cap or closure, the latter will be firmly pressed up against the shoulders and the cap or closure will thus be reinforced where the improved gripping means is applied.

It will be understood that changes in the general proportions and dimensions of the disk or closure and the improved gripping means may be adopted at will, and the thickness of the material of which the improved gripping means is formed may also be modified without departing from the spirit of the invention.

What is claimed as new is:

l. A cap or closure for milk bottles and the like, consisting of a disk having a central slot therethrough and a stiff gripping means comprising an upper gripping member of greater length than the length of the slot and provided with centrally disposed integrally formed depending securing members of less width than the length of the said gripping member and inserted through the said slot and reversely bent against the underside oi the disk, angular shoulders of equal length being formed at opposite sides of the securing members by the greater length of the gripping members relatively to the securing members, said shoulders extending outwardly beyond the opposite terminals of the slot and drawn in tight bearing contact with the top of the disk by the reversely bent securing members to prevent the gripping member from being forced through the disk and to cause the shoulders to close the ends of the slot.

2. A cap or closure for milk bottles and the like, consisting of a disk having a central slot and a gripping means constructed of doubled relatively stifl material having an upper gripping member of greater length than the length of the slot and securing members integrally depending from the center of said gripping member and of less width than the length of the gripping member but equal in Width to the length of the slot and inserted through the latter and closely bent against the underside of the said disk, the gripping means having shoulders provided at the lower portions on opposite sides of thesecuring members, said shoulders beingdrawn in tight engagement with the upper surface of the disk and closing over the ends of the slot when the securing members are bent against the underside of the disk.

3.
